The equivalent resistance is the overall effect all of the resistances in a circuit has. Put another way, it is the value a single resistor in a circuit would have to be in order to have the same effect as all of the resistors resistors combined in a given circuit.

∙ 13y agoIn parallel connection of resistors, inverse of equivalent resistance is the sum of inverse of the individual resistance. That means the total resistance in a parallel circuit can be found as expressed below:
1/R = 1/R1 + 1/R2 + 1/R3 + ...
Where R is the Total ( Equivalent ) Resistance, whereas R1, R2, R3 ... are the individual resistances of the parallel circuit.

Which type of resistance training requires muscles to move against resistance through an entire range of motion?
The type of resistance training that involves muscles to move against resistance through an entire range of motion is called Isokinetic exercise. Here's the definition from the Glencoe Health Book: Isokinetic exercise- activity that involves resistance through an entire range of motion. I hope that helped you! :)
What happens when a light bulb is broken in a series circuit?
In that case, the entire circuit won't work.
Does current in the lamps occur simultaneously or does charge flow first through one lamp then the other and finally the last in turn?
Currents are either flowing or they are not. However these lamps are hooked up, series or parallel, the minute current starts flowing through a circuit it is moving throughout the entire circuit.
How does series circuit travel?
The electricity follows the entire length of the wire. if any part of the circuit is broken, all the electricity stops moving in the circuit.
What is the role of insulators such as plastic rubber and cloth covering wires and other conductors in a circuit?
Insulators are used to keep electrical currents in the circuit. If they do not follow the entire circuit, it would be a "short circuit".
If a parallel circuit shorts at the battery will the entire circuit short out too?
If at battery,parallel circuit shorts then equivalent resistance of circuit becomes approximately 0 Ohms,and therefore as current follows low resistance path infinite amount of current due to low resistance will flow through the wire so,entire parallel circuit will short out,but wire will burn and battery may get damaged.

What is dead short circuit?
A short circuit which offers very low, practically zero, fault resistance is called "dead short circuit". further more it bypasses the entire load current through itself.
What is Power that is applied to an entire circuit consisting of resistance capacitance and inductance is called?
The unit of power measured is watt, irrespective of resistance, capacitance or inductance of the circuit.
Why doesn't current decrease in series resistance circuit though resistance opposes current?
If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.
How do you find power in a series circuit?
Power dissipated by the entire series circuit = (voltage between its ends)2 / (sum of resistances of each component in the circuit). Power dissipated by one individual component in the series circuit = (current through the series circuit)2 x (resistance of the individual component).

Does current depends on its resistance?
The current flow in an electrical circuit depends on the applied electromotive force (EMF, measured in volts), and the total resistance along the entire circuit. Rising EMF or dropping resistance cause increased current flow
Does the current generates if there is no resistance in the circuit?
You can have current without resistance. You would just have zero voltage drop across that zero resistance.However, the question is very interesting, because if you really had zero resistance in the entire circuit, it would be impossible to have any voltage at all without generating an infinite current, so the answer in the theoretical case is no, you can have no current, nor voltage, if there is no resistance at any point in the circuit.
What is voltage drop with 30 volts across 25 ohm resistor?
To tell you that we need to know the resistance of the entire circuit.
What is resistance on something that is shorted?
It depends on weather it is in a parallel or series circuit. In parallel the entire circuit it is in parallel with is shorted out. In series the total resistance decreases by the amount of the resistor that shorted out. Resistors usually open or change value with use.
How short is a shortcircuit?
A short circuit is so short that all the current in the entire network prefers to pass through it! Actually, whenever in a network/circuit there are two parallel paths for the current to flow, the current chooses the path of least impedance. As such, a circuit with no impedance of any sort is called a short circuit cuz the entire current passes through it.
Why does not it matter where you measure the current in a simple circuit?
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
